FEEDING AND REGULATING MECHANISM FOR ARC-LAMPS.

SPECIFIGATION forming part Of Letters Patent NO. 677,005, dated June 25,1901.

Application filedlebruary 6, 19 01- Seria1No.46,Z44- (Ndmorleh) To allwhmn it may concern:

Be it known that I, WILLIAM E."/VALDRON, a citizen of the United States,residing at Colorado Springs, in the county of El Paso and State ofColorado, have invented new and useful Improvements in" Feeding andRegulating Mechanism for Arc-Lamps, of which conductor.

the following is a specification.

This invention relates to certain new and useful improvements inare-lights, the purpose being to provide an arc-lamp .or headlight forelectric cars or in other such places where the lamp is subjected tojars and to intermissions in the flow of the current such as areincident when a car passes a crossing or over a rough joint, theconstruction being designed to provide a lamp with a rigid frame andmeans wherebythe arc will be instanta-,

elevation; and .Fig. .3 is [afront elevation of.

feed being accomplish'edby gravity.

My'invention consists in the construction and organization of the parts,as will be hereinafter set forth, and specifically pointed outintheclaims. I

In the accompanying drawings, Figure 1 is a front elevation of-anarc-lampconstructed Fig; 2 is a side the upper portion of a'lamp,showinga modification. i i V v To the main frame or back-piece A isbolted or otherwise attached the lower carbon holder A, said holder Ibeing provided with means whereby the lower carbon H can be adj usted tothe desired height, the lower-carbon holder A vprojecting from theback-piece, as shown.

To the upper portion of the main frameis secured a frame B, it beingseparated from the back-plate by suitable insulations a, and

this frame B is shaped to provide a laterallythe part B, and throughthese guides pass the v I upper-carbon carrier L, towhich the uppercarbon is secured by means of a clamp F. The carbon-carrier is adaptedto move freely through the guides E E, and in order to insure electricconnection between the wire or coil of the electromagnet and thecarbon-carrier a wire cis attached to both of the guides and'to. theclamp F, the wire adjacent to the clamp being bent spirally to form acoil D, which permits the upper-carbon carrier moving vertically. To thevertical portion 1) of the frame Bis pivoted the armature, comprisingabar'J, which carries a metaliplate I, located above the core of themagnet. The I bar J may be made of non-conducting mate- 8o rial and hasat itsend nearest the carbon an aperture through which passes the shankof a movable coupling m, the rod from which the coupling is made beingthreaded to receive a nut which contacts with the bar J, 5 the oppositeend of the bar being formed -into a ring which engages an eye orperforation through the ring-clutch K. The nut and threaded shank of thecoupling provides means for adjusting the armature to suit the 0conditions under which the lamp is used.

The ring-clutch K encircles the carbon holder L, being placedbetweentheguides therefor, so that it may bear upon the lower guide E.The ring-clutch is maintained normally in a horizontal position, so thatthe carbon-holder can slide freely therethrough by springs, and, asshown in Fig. 3, a single spring m encircles the carbon-holder and bearsagainstthe ring-clutch and the upper- 10o carbon guide, or I may attacha spring 70 to the bar J and to the stud which projects from in ahorizontal position.

the vertical portion 1) of the frame B, and on the other side there is aspring 70, oneend being attached to the ring-clutch and the other end tothe frame, The different arrangement of springs I consider equivalents,as they both serve to move the armature away from the magnet and tend tohold the ring-clutch It will be noted that when the ring-clutch ishorizontal the upper carbon will be fed downward, by gravity; also, thatwhen said. clutch is horizontal the armature is 'out of contact with thecore of the magnet I In practice the end of thewire from the coil of theelectromagnet may be formed into a coil and attached directly to theclamp F, the other end of the core being fastened to a binding-post, awire leading therefromtoa resistcurrent passes through the coils of theelectromagnet, energizes the soft-iron core thereof,

and draws the armature down, tilting the clutch-ring, which responds tothe movement of the armature'and strikes the arc, insuring the properworking of' the lamp, and as the carbon burns away the circuit isbroken, which permits the carbonto move downward sufficiently toreestablish the arc. Thisac- I tion takes place instantaneously. Underall conditions the carbonsare held in the same relative position by theelectromagnet, so that under all variations inthe current the lamp givesa steady even light'and is.not eXtinguished until the circuit isentirely broken. Thus the lamp operates under extreme variations of thecurrent and is not affected by jar or vibrations, such as are present onelectric cars. Two or'more lamps may be placed in series or may be usedindependently, and all shunt-circuits are avoided. I I v I Whennecessary or deemed advisable, the electromagn'et, as described, may beinverted, thusplacing the armature under the magnet, reserving the samegeneral construction.

' Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, is I I 1. In an arc-lamp, the combination of amain supporting-frame, a lower-carbon holder in electrical connectiontherewith, a frame attached to the upper part of the mainsupporting-frame and insulated therefrom said upper frame having guidesfor the upper carbon and a projecting portion, anelectric magnet v andits armature the armature being carried by the projecting portion of theframe, a ringclutch mounted between the guides, means as a spring orsprings for holding the ring-clutch horizontally upon one of thecarbon-guides and the armatureaway from the coreof the electromagnet,substantially as shown.

2. In an arc-lamp, the combination of a main supporting-frame and alower-carbon holder which is rigidly attached thereto, of a frame havingguides for the upper carbon, a laterallyprojecting portion constructedto an electromagnet and an armature therefor,
